If CBS is actually getting tired of Tony Romo, as clickbait titles suggest, then he would be a great voice in the ear of the QB as a QB coach, and probably a top notch offensive coordinator. He loves the game, is a student of the game, and would be tremendously effective at designing plays. Few collarbone injuries in the offensive coordinator world, right?
Yes, the Dak-Romo relationship is probably a bit icy, but that can be a good thing too, both would have to be intentionally professional in their discussions.
